Everybody knows ‘the speed of light’ is fast. The only thing faster is Chuck Norris, who, the legend goes, can turn out the lights and be under the covers before the room gets dark.

But just how fast is light?

And does it always move the exact same speed? Can we use light to transmit data in a way that harnesses its speed as one of the fastest actors in the known universe? There is has always been a dream of teleportation or using wormholes to jump across time and space at warpspeed, but some scientists now believe that such technology may be more feasible than once thought.

And even if we are centuries away from transporting anything meaningful at the speed of light, the idea of lightspeed may soon jump from the realm of Star Wars to something much more tangible.

Topological randomness may be the answer for lossless electronics and making the nuts and bolts of quantum computers. Complete randomness in the structures of superconductors and insulators could lower the requirements of pristine crystalline ordering — and make them more accessible to industry.Read More

The NOvA collaboration has announced its first results using antineutrinos, and has seen strong evidence of muon antineutrinos oscillating into electron antineutrinos over long distances, a phenomenon that has never been unambiguously observed.Read More

By comparing different types of remote atomic clocks, physicists have performed the most accurate test ever of a key principle underlying Albert Einstein’s famous theory of general relativity, which describes how gravity relates to space and time.Read More

An observation made by the CMS experiment at CERN unambiguously demonstrates the interaction of the Higgs boson and top quarks, which are the heaviest known subatomic particles. This major milestone is an important step forward in our understanding of the origins of mass.Read More

Some particles that can be in two places at the same time and are not just particles but also waves, in this case, fermions, appear to move in even weirder ways than previously thought. Theoretical physicists applied extreme computing power for a week to predict the movements of fermions by including quantum optics, or light-like, ideas in their mathematical, theoretical modeling.Read More

Physicists has demonstrated a way to conduct electricity between transistors without energy loss, opening the door to low-power electronics and, potentially, quantum computing that would be far faster than today’s computers. Their findings involved using a special mix of materials with magnetic and insulator properties.Read More

Scientists have found a new way to transfer quantum information. They propose using tiny mechanical vibrations. The atoms are coupled with each other by ‘phonons’ — the smallest quantum mechanical units of vibrations or sound waves.Read More

A research team has developed a new quantum switching scheme that gives them access to new and hidden states of matter. If researchers can learn to control the hidden state, further stabilize it and determine whether it’s suitable for quantum logic operations, it could allow researchers to use it for quantum computing and other practical functions.Read More
